Specification of Letters ratat.

To all euhom it may concern:

Be it known that I, HARRY B. ARNoLo, a

' citizen of the United States, and a resident of New Britain, in thecounty 0 Hartford and State of Connecticut, have invented a new andImproved Couch-Bed, of which the following is a specification.

My invention relates more especially to that class of devices which maybe used for couch purposes, and which may be unfolded to serve as a bed,and an object of my invention, among others, is to provide a device ofthis class that shall be extremely simple in its construction, thatshall be practically effective for the purpose for which it isconstructed, and one that may be easily operated.

One form of couch embodying my invention, and in the construction anduse of which the objects herein set out, as well as others, may beattained, is illustrated in the accompanying drawings, in which Figure 1is a view in end elevation of a couch em odyin'g my invention, the partsbeing shown in their folded condition.

Fi 2 is a like View showin the arts extended or unfolded, the mattressesbeing omitted.

Fig. 3 is a view in elevation of the couch looking from theback towardthe front, the

parts being in their unfolded condition.

Fig. 4 is a plan view of a portion of the couch showing the parts intheir unfolded position.

The couch bed herein illustrated and described, and embodying myinvention, has two endmenibers 01' frames, each being of an invertedU-shaped form, the branches of which constitute front legs 6, and backlegs 7 the connecting part constituting a cross bar 8. The back legs 7have'a secured to them, preferably at some distance fromtheir lowerends,and the front legs 6 are rigidly supported as by a frame bar 10,preferably of angular construction, which frame bar is secured at eachof its endsto a post 11, each of said posts being r1g1dly secured to abracket 12, each ofwhich brackets is rigidly secured to one of the frontlegs 6. The end members, frame rod, frame bar,

strut ends and brackets constitute the main or supporting frame of thecouch.

A folding frame, 'supported upon the maln frame, consists of a body orback portion, an

extensible portion, and a connecting portion. 7

The body or back portion is composed of end bars 13, connected at theirback ends by a head bar 14, and a wire fabric 15 secured to the endbars. The connecting or rocking portion is composed of link bars 16 atthe ends of the portion, pivotally connected at their backends \vith'theend bars 13, and to which link bars The link bars 16 are pivotallysupported at the upper ends of the posts 11, upon which posts the linkbars have a rocking movement. Studs 30 proj cct from the sides of thelink bars near one end and edge as shown in dotted lines in Figs. 1 and2.

The extensible portion of the folding frame is composed of end bars 17pivotally connected at their back ends to the link bars the fabric 15,so that the two fabrics overlap one another. A foot'rail 19 rigidlyconnects the end bars 17 and folding legs 20 are pivotally secured tothe end bars 17 near their outer or front ends, all of these partscomposing the extensible portion of the structure.

A leg operating rod 21 is pivotally connected to each of the legs 520and to one of the front legs 6. 'A locking link connection of the legoperating rods 21 near the connection of the latter with the legs 6, andthe opposite end of each locking link connection is slotted to receive apivot pinfrom'o'ne of a pair of locking links 26. This pivot pin islocated near the adjacent ends of each of the'pairs of locking links,one member of each pair 0 said links being pivotally secured to thebracket 12, and an end of the'other member of each pair of links beingpivotally connected tothe link bar 16.

A. mattress 23 is secured to the surface of the folding frame, and acushion 2a is secured to the opposite surface of the'extensibleportionof the folding frame.

Fromthis construction it will be observed that when the extensibleportion of the folding frame is swung upwardly, in the operathe fabric15 is secured.

elating rods 21 will pivotally portion when the winging movement willtake place at the pivots at the upper ends of the strut ends 11, a partof this extensible swinging. movement, under certain conditions, takingplace simultaneously at the pivots at the outer ends of the link bars16' and at the upper ends of the strut ends 11. This extensible swingingmovement disposes the parts in the position shown in Fig. 2, the frontend or edge of the body portion of the folding part of the couch beingdrawn upwardly from the posit-ion shown in Fig. l and its opposite edgebeing slid backwardiy up the guides or supports 25 secured to the framerod 9 and supported in inclined position, as shown in Figs. 1 and 2 ofthe drawing, to receive the head bar 14, each of these guides 25 havingan extension from its back end to support the head bar, when the couchis in its unfolded or extended position.

As the extensible portion is swung as described,.to its extendedposition, the leg opact to swing the legs upon their pivots, the ends ofthe legs first moving away from the end bars 17 and then moving towardsaid end bars and past them to the position shown in Fig. 2 of thedrawing. The locking link connections 22 are connected to the legoperating rods 21, in such manner that when the couch has been unfolded,the pins upon the locking links connection may operate to draw thelocking links into their locked position as the parts are finallyopened. As the folding operation takes place, the joint 81 connecting.each pair of locking links may be provided with any suitable stop forpreventing them from breaking forward. It will be noted that the slotsin the locking link connections, permit the extensible portion of thestructure to be swung partially to its closed position before thelocking links are operated to unlock the parts, this latter operationbeing effected by the engagement of the ends of the slots with the pivotpins, which engagement moves the locking links to unlock the parts andpermits them to be swung to the position shown in Fig. 1. The end bars17 of the extensible portion swing upon the pivots at the outer or frontends of the link bars 16 in which movement the locking link connections22 move independently of the locking links 26 by reason of the pin andslot connection. Just before the ends of the slots engage the pins tounlock said link, as above described, the edges of the end bars 17 aremoved against the studs 30 and the link bars 16 are thus caused to swingupon their pivots at the ends of the posts 11. When the parts have beenswung to their closed positions as shown in Fig. 1 of the drawings, theedges of the end bars 17 resting against the studs 30 (see dottedoutlines in Fig. 1 of the drawings) prevents any swinging movement ofthe link bars 16, such as would cause the 7 upon the cross barsstructure to collapse for the reason that the end bars 17 are supportedupon the studs 30. In this position it will be noted that the front edgeof the body portion of the folding frameis lowered to create a space orcavity 27 between the extensible portion and the body portion, thiscavity occurring at the front edge of the latter, the back edge beingclosed by the meeting surfaces of the folded mattress. ceptacle forpillows or like articles.

It will be noted that the pivots at the ends of the link connections 22are so located with respect to the pivotal points of connection of therods to the legs 6 that the parts will be locked against closingmovement when the structure is unfolded. Projections 28 from the ends ofthe foot rail 19 are located to rest 8, when the parts are intheirclosed position, and this forms a support or rest for the foldingframe.

The description and drawing herein discloses my invention as embodied inan approved structure, but this may be departed from to a greater orlesser degree and yet be within the spirit and intent of the invention.
